Receiver antenna synchronization and carrier frequency offsets pre-mitigation for distributed massive MIMO system

This paper presents a receiver antenna synchronization and carrier frequency offsets pre-mitigation procedure, which is proposed for distributed massive MIMO system. The technique's performance is dependent to the SNR as well as the number of OFDM symbols per transmission packet. It has been shown that the procedure is working using a rapid prototyping platform based on WARP board. The MIMO system employing 16 receiver's antenna has been shown to provide approximately 15dB transmit energy saving gain compared to a two-antenna system.
